With an output power rating of up to 2.4W/channel into 4Ω bridge-tied
speakers at a THD+N of 1% (up to 3W at 10% THD+N), the PAM8009 provides
a high-power, low-cost capability for driving the small internal
speakers typically found in LCD monitors and similar types of
applications. A separate connection provides for single-ended driving of
stereo headphones with a power output of 60mW into 32Ω loads. A DC
volume control with hysteresis allows for gain adjustment from -80dB to
+20dB in 64 steps. Automatic gain control and under-voltage protection
functions prevent speaker damage due to output clipping and will shut
down the amplifier before an input device generates a ‘pop’.

The PAM8009 operates from 2.8V to 5.5V supplies, consuming a quiescent
current of 7mA at 5V. Thermal and over-current protection is
incorporated with auto-recovery and the device is supplied in
power-enhanced packages to aid power dissipation. A mute pin allows the
speaker/headphone outputs to be quickly disabled, also helping to save
power. To further reduce power consumption a shutdown mode turns off the
amplifier’s bias circuit. Further information is available at
